Anellotech推出Plas-TCatTM新的工藝技術,可將廢塑膠直接回收利用為加工化學品。


將多種塑膠廢料轉化為最初化合物

美國Anellotech推出了一項新技術,該技術可以將多種塑膠廢料直接轉化為加工化學品。新的Plas-TCatTM工藝是一種具有成本效益的技術,它將大量廢塑膠直接回收利用為商品化學品,例如烯烴、烷烴和芳烴化學品,其特性與石油基同類產品相同。然後,製造商可以使用這些化學物質製造純淨的塑膠。
 

Plas-TCat工藝具有將塑膠薄膜直接轉化成有價值的化學品的潛力

Anellotech希望開發Plas-TCat,以便可以轉換當今使用的大多數塑膠材料(例如複合膜、混合塑膠和具有生物質的塑膠)。Plas-TCat可以處理含氧聚合物,這是熱解工藝的重要優勢,而熱解工藝生產的複雜油混合物需要在蒸汽裂解裝置中進行升級和額外轉化。
 

Plas-TCat未來展望

由於有價值產品的潛在高回收率,我們希望在不執行塑膠廢物收集並且目前缺乏隔離廢物塑膠流的收集基礎設施的地區使用Plas-TCat。通過支付廢塑膠的費用,Plas-TCat提供了經濟誘因來應對塑膠污染,尤其是在海洋塑膠污染源頭大量的發展中國家。Anellotech正在尋求與知識淵博的戰略合作夥伴合作,以提供開發資金及有關廢塑膠供應鏈和機械處理方面的知識,以幫助加速該項目。

Sustainable technology company Anellotech is significantly expanding its programme with Plas-TCatTM, a new process technology aiming to convert a wide range of plastic waste directly chemicals – which can then be used to make new, virgin plastics.
95 per cent of plastic packaging material is annually lost to the economy after a single use and often ends up in combustors, landfills or polluting the ocean. By leveraging Anellotech’s existing Bio-TCatTM process – which converts biomass bio-based chemicals and biofuels – Plas-TCat has demonstrated encouraging results in lab studies using pure plastics.
Plas-TCat has the potential to offer a new, cost-effective process which will recycle significant quantities of waste plastics directly commodity chemicals. Once in the recycling , waste plastics could be converted commodity chemicals such as olefins, alkanes and aromatic chemicals, which are identical to their petro-based counterparts which are currently used by manufacturers to make virgin plastics.
Anellotech wants to develop Plas-TCat so it could convert the majority of plastic materials used today, including composite films. Anellotech aims to use its Bio-TCat lab and TCat-8 pilot s to feed in plastics waste, eventually developing and designing a commercial plant to efficiently make commodity chemicals at large scale, using the same basic process configuration.
Anellotech has expanded its development program, which is expected to last several years. The company has planned studies to ensure that the Plas-TCat process is robust and capable of running long term, on a range of real-world waste plastics feedstocks, with all the impurities that come with them. Anellotech’s TCat-8 pilot plant extensively ran 24/7 with biomass and the company expects it to do the same with plastics.
“Plas-TCat has the potential to transform plastic waste such as composite films, mixed plastics and plastics with biomass – such as paper labels – directly valuable chemicals. It can handle oxygenated polymers, an important advantage over pyrolysis processes that produce complex oil mixtures which require upgrading and additional conversion in steam crackers,” said David Sudolsky, President and CEO of Anellotech.
“With potentially high yields of valuable products, we are keen to use Plas-TCat in areas where plastic waste collection is not enforced and collection infrastructure to isolate waste plastics streams is currently lacking. By allowing payment for waste plastic, Plas-TCat provides economic incentives to tackle plastics pollution, especially in developing countries where much of the ocean plastic pollution originates. We are excited about this new venture and are seeking engagement with knowledgeable strategic partners to provide development funding, as well as knowledge in waste plastics supply chain and mechanical handling, to help accelerate this project.”

US-based sustainable technology company Anellotech has unveiled a new technology which converts a wide range of plastic waste directly processing chemicals.
The Plas-TCatTM technology leverages Anellotech’s existing Bio-TCatTM process and has so far demonstrated “encouraging results” in lab studies, Anellotech said in a release 6 Dec.
Bio-TCat is a thermal catalytic process for converting biomass BTX - a mixture of benzene, toluene and xylene - aromatics which are chemically identical to their petroleum-based counterparts.
The new Plas-TCatTM process is billed as a cost-effective technology which will recycle significant quantities of waste plastics directly commodity chemicals, such as olefins, alkanes and aromatic chemicals, with properties identical to their petroleum-based counterparts.
The chemicals can then be used by manufacturers to make virgin plastics.
“Plas-TCat has the potential to transform plastic waste such as composite films, mixed plastics and plastics with biomass – such as paper labels – directly valuable chemicals. It can handle oxygenated polymers, an important advantage over pyrolysis processes that produce complex oil mixtures which require upgrading and additional conversion in steam crackers,” ed David Sudolsky, president and CEO of Anellotech.
The New York-based company now intends to further develop Plas-TCat to convert the majority of plastic materials used today, including composite films.
As part of this, Anellotech will feed in plastic waste its Bio-TCat lab and TCat-8 pilot s in Silsbee, Texas, with the aim to eventually develop and design a commercial plant to manufacture commodity chemicals at large scale.
The company has also extended its development programme to include further studies to ensure that the process is robust and capable of running long term, on a range of real-world waste plastics feedstocks, with all the impurities that come with them.
With potentially high yields of valuable products, the technology can be particularly useful in areas where plastic waste collection is not enforced and collection infrastructure to isolate waste plastics streams is currently lacking.
“Plas-TCat provides economic incentives to tackle plastics pollution, especially in developing countries where much of the ocean plastic pollution originates,” Sudolsky added.
